Abstract: The invention is an improved collet design for arc welding torches. The collet tip is asymmetrically tapered. The collet tip bears on the interior surface of an adjacent sleeve which is appropriately flared in the rearward direction so as to receive the tapered collet tip. The sleeve also has an opening through which the electrode passes. The asymmetry of the collet-sleeve interaction causes the collet to be laterally displaced thereby gripping the electrode between the collet and the sleeve opening.The improved collet also includes a spring fastener means for connecting the rear end of the collet to the back cap of the torch head.

Abstract: A gas consuming electric welding torch has a swiveling torch head which is angularly oriented with respect to the torch handle. Inert gas and electrical current flow through a conductive passageway into a swivel body. A swivel fastener extends through the swivel body and is fastened to threads in a piece extending radially from the torch head. Insert gas may flow through the swivel fastener and into the torch head.

Abstract: A pipe cutting machine capable of cutting saddles and mitres and combinations of saddles and mitres is disclosed. The machine uses the rotation of the pipe itself to power a cam drive assembly. The cam drive assembly powers a saddle cam and a mitre cam. The saddle cam and the mitre cam may be set such that a specific mitre cut, saddle cut, or combination of saddle and mitre cut may be accomplished. A cable assembly translates the rotation of the saddle and mitre cams to a torch carriage. The torch carriage in turn translates its movement concurrently to the torch itself, thereby cutting the exact saddle, mitre, or combination of saddle and mitre cut desired.
